We honestly need a network that can't suddenly be overthrown by one guy bringing in a server farm doubling the Exahash rate. That's dangerous.
That'd be like if Jeff Bezos bought half of Congress and suddenly gained the ability to pass whatever legislation he wanted because he owns the majority voting power.
That's exactly why we need ASICS actually. If you want to affect the network you gotta buy them and contribute to the hashing power. ASIC resistance wrecks that incentive structure.
